Suarez (back) is expected to throw a bullpen session either Sunday or Monday, Todd Zolecki of MLB.com reports.

EDGE Analysis

Suarez is eligible to return from the 15-day injured list Wednesday and the left-hander will take the first step towards being activated when he throws his first bullpen session. There was optimism from the Phillies that Suarez would be able to return during the team's four-game series in Arizona beginning Thursday, but that now seems unlikely. The left-hander was placed on the IL with lower-back soreness last week and considering Philadelphia is 5.0 games up on Atlanta for first place in the NL East, the team will likely be cautious in their efforts to get him back.
